SEWAGE-EJECTOFL Specification of Letters Patent.

Patented May 22, 1906.

Application filed October 11,1905. Serial No. 282,227.

To all whom it may concern:

Be it known that we, FREDERICK Mnrnns, residing at Chicago, in the county of Cook and State of Illinois, and CnAnLns T. HILDE- BRANDT, residing at Dayton, in the county of Montgomery and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Sewage-Ejectors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sewage-ejectors.

The invention resides in the method and arrangement of the pumps whereby the contents of the sewer-basin is reduced to a certain level, and maximum quantities of the surface matter accumulating within the catch-basin is removed therefrom.

Preceding a detailed description of the invention, reference is made to the accompanying drawing, which consists of a cross-sectional view of a catch-basin, showing the arrangement of the suction-pumps and their connections with said basin.

In a detail description of the invention, similar reference characters indicate corresponding parts.

1 designates acatch-basinwhich is connected at opposite sides with vertical suctionpumps 2 and 2. The connection of pump 2 is through suction-pipe 3, which communicates with the bottom of the catch-basin. At the opposite side of the catch-basin the elevated pump 2 is placed and is connected with said basin through suction-pipe 3 above the point of connection with the suction-pipe 3. The objects of the pumps are to reduce the contents of the catch-basin to acertain level below the suction-pipe 3, and an additional purpose of pump 2, which, as before stated, is the elevated pump, is to remove the foreign substances which accumulate on the surface of the water Within the catchbasin. On the side of the basin on which the suction-pump 2 is located means are pro vided for forcing the contents of the basin toward the suction-opening 3 in order that when the contents of the basin reach the level of the suction-pipe 3 the surface contents will be forced toward said opening 3. These means consist of an outlet-pipe L,which connects with the discharge-pipe 5 of the pump 2. This pipe 4 has a spraying-nozzle 6, which is projected into the basin approximately in a line with the suction-pipe 3. hile the pumps are working, there is an injection of water into the basin,which tends to cause a flow of the contents of said basin toward the suction-pipe 3. The floats 7 and 7 form no part of the present invention. and are only incidentally mentioned. Each. of these floats has a rod 8, which is connected with an automatic switch (not shown) and by means of which the motor operating in connectionwith each pump is controlled. The float 7 is adjusted in order to permit the operation of pump 2 after the pump 2 has stopped. While it may appear from the drawing that the floats and their guidecasings are in line with and adjacent to the spraying-nozzle 6 and the suction-pipe 3, it will be understood that said floats and said guide-casings stand back and away from proximity to said noz- Zle and said suction-pipe and offer no obstruction to theflow to the suction-pipe 3.

Having described our invention, we claim In a sewage-ejector, a catch-basin, a suction-pump connected With the bottom of said basin, a suction-pump connected with the opposite side of said basin at an elvation, and a spraying device connected with the dischargepipe of the lower pump and adapted to inject water into the basin in a direction toward the inlet to the elevated pump, whereby, means are provided for reducing the contents of the basin, and for removing the surface matter from the contents of said basin, substantially as specified.

In testimony whereof we affix our signatures in presence each of two witnesses.
